Abstract

The product of the present invention comprises flexible tray cables and metal-clad cables designed for use with adjustable speed drives, and terminations coupled therewith. The cables comprise, generally, three phase conductors, three ground conductors and fillers, and are wrapped with copper tape and other elements. The terminations comprise a plurality of connectors and a plurality of flexible, tinned-copper braids acting as the shield termination for the copper tape. More detailed and other embodiments of the present invention are disclosed in the specification hereof.
